Using Fly without owning a Pokémon that knows it

[MikeTwo2]

Hey guys,
Just looking for a bit of help with RMXP, I need to allow the player to be transported to a place of his/her choosing within an event (like the dungeon choosing in PMD)
My solution was to open up the fly screen so that players can fly to "dungeons" they've been to before, and there won't be any tacky choice screens. I soon realised this was tricky to do, however, without actually giving the player a Pokémon that knows Fly. As such have resorted to the forums.
Anyone know how I go about this?
Many thanks,
Mike

P.S. One last quick question: How do I copy across the variable catchRate into my own Script Section?

If the only way the player can use Fly is through your event transport system, then you can edit its scripts so that it no longer requires that a player's Pokémon knows Fly in order to use it. That is, delete what you need to from HiddenMoveHandlers::CanUseMove.add(:FLY,proc (probably most of it; just return true like Sweet Scent's does).

Here is some stripped-down code which you can use to use Fly:

scene=PokemonRegionMapScene.new(-1,false)
screen=PokemonRegionMap.new(scene)
ret=screen.pbStartFlyScreen
if ret
  $PokemonTemp.flydata=ret
  Kernel.pbUseHiddenMove(nil,PBMoves::FLY)
end

You'll also want to remove the "Pidgeot used Fly!" message and the hidden move animation for using Fly, because they're not appropriate.

However, if you want to be able to use Fly normally as well, then you'll need to create a new method containing (mostly) the above code and Fly's effect (minus the message/animation as mentioned). Call this method from your event.


The catch rate for a species can be loaded with the following code:

dexdata=pbOpenDexData
pbDexDataOffset(dexdata,species,16)
catchrate=dexdata.fgetb
dexdata.close

You can use this anywhere, so long as you have a species to find the catch rate of.

I don't want to be able to Fly normally too, but what method do I call in the event?

The catch rate for a species can be loaded with the following code:

dexdata=pbOpenDexData
pbDexDataOffset(dexdata,species,16)
catchrate=dexdata.fgetb
dexdata.close

You can use this anywhere, so long as you have a species to find the catch rate of.

This worked perfectly, thanks.
Which bit of this do I change to get base HP?

catchrate=dexdata.fgetb

Sorry for all the questions...

Thanks
Mike

You can create a new method with the stripped-down code I gave you, and call that.

To get the base HP, use the same code as for catch rate but replace the 16 with 10.

Thanks for all your help :D
